Proline Promass A 100 Modbus RS485 Installation 6.1.2 Requirements from environment and process Ambient temperature range Measuring device Safety Barrier Promass 100 40 to +60 C ( 40 to +140 F) 50 to +60 C ( 58 to +140 F) (Order code for "Test, certificate", option JM 40 to +60 C ( 40 to +140 F) If operating outdoors: Avoid direct sunlight, particularly in warm climatic regions. System pressure It is important that cavitation does not occur, or that gases entrained in the liquids do not outgas. Cavitation is caused if the pressure drops below the vapor pressure: In liquids that have a low boiling point (e.g. hydrocarbons, solvents, liquefied gases) In suction lines Ensure the system pressure is sufficiently high to prevent cavitation and outgassing. For this reason, the following mounting locations are recommended: At the lowest point in a vertical pipe Downstream from pumps (no danger of vacuum) A0015594 Thermal insulation In the case of some fluids, it is important that the heat radiated from the sensor to the transmitter is kept to a minimum. A wide range of materials can be used for the required insulation. NOTICE Electronics overheating on account of thermal insulation! Observe maximum permitted insulation height of the transmitter neck so that the transmitter head is completely free. Heating NOTICE Electronics can overheat due to elevated ambient temperature! Observe maximum permitted ambient temperature for the transmitter ( 19). Depending on the fluid temperature, take the device orientation requirements into account. Endress+Hauser 19

Installation Proline Promass A 100 Modbus RS485 Heating options If a fluid requires that no heat loss should occur at the sensor, users can avail of the following heating options: Electrical heating, e.g. with electric band heaters Via pipes carrying hot water or steam Via heating jackets Using an electrical trace heating system If heating is regulated via phase angle control or pulse packages, magnetic fields can affect the measured values (= for values that are greater than the values approved by the EN standard (sine 30 A/m)). For this reason, the sensor must be magnetically shielded: the housing can be shielded with tin plates or electric sheets without a privileged direction (e.g. V330-35A). The sheet must have the following properties: Relative magnetic permeability µr 300 Plate thickness d 0.35 mm (d 0.014 in) Vibrations The high oscillation frequency of the measuring tubes ensures that the correct operation of the measuring system is not influenced by plant vibrations. 6.1.3 Special mounting instructions Outlet run for peripheral device If a pressure and temperature measuring device are installed downstream from the measuring device, make sure there is sufficient distance between the two devices.
